Dynamic preselected selection in PowerBI slicer

Hi IshaDahra 

As you can see i have created a calculated column

In which i have named for current month to show Latest Month ( in calculated col)

and in the slicer i just selected Latest Month, Now whenever the new month data is added then that calculated column is re-run when it get refresh then again Latest Month will give the current month which is added into it .

I have just tried with a sample by adding next month for 1999. and it's working 



If this answers your questions kindly accept it as a solution and give kudos.
